Fig. 2 is asectional plan -Wfard-hottle maybe-at rest in such position view of the driving mechanism-forrot'atingas to be caught at ldiametrically opposite as the pocketedtransferring-Wheel. 'Fig. 13 is points between the approaching tooth1201? a vertical sectional view of the .driving tl1e-1wheel 8and-thejunction 13 of=the stamechanism and the hubiportion of thewheel..tionary-guides 5 and 9, obviously resulting in crushing the bottleunless the movement of the wheel 8 is arrested and the bottle moved outof its centered position of engagement. The latter mentioned protectiveasxtions are accomplished by my present inxention.

Refers-1g now to Figs. 2 and 3, a driven shaft 1st extends upwardlythrough the table 6, and carries a fixed collar 15. The collar and upperportion of the shaft support the hub portion 16 of the wheel 8, thelatter comprising spaced upper and lower plates 1'? and 18 radiatingfrom the hub. The wheel 8 is loosely rotatable on the shaft 11 whichextends substantially above the wheel.

liilounted on the upper end of shaft 14 is a toothed member 19, securedto the shaft as by the key 20 and the end screw 21. A ring is mounted onthe upper surface of the wheel 8 concentric with the shaft 14, andsecured to the wheel 8 as by means of bolts The ring 22 preferably isscrew threaded on its outer periphery to removably receivea cover 24forming a casing over the enclosed mechanism. The ring 22 is providedwith an inner lug or flange 25 on which is pivotally mounted one end ofa bifurcated dog 26. A roller 27 preferably is pivotally supported inthe other end of the dog 26, the dog being positioned to swing theroller in and out of engagement with the teeth and intermediate pocketsof the member 19. A pin 28 is secured to the dog 26, and a similar pin29 is mounted on the ring 22. A spring 30 is mounted on the two pins andtensioned to normally hold the roller 27 in engagement with one of thepockets 31 in the member 19.

The equi-spaced pockets 81 are equal in number to the pockets 7 in thewheel 8, so that the roller 27 may be positioned in either of thepockets 31 and normally maintain the wheel 8 in correct relation betweenthe bottle receiving pockets 7 and the elevators 2. The tensioned spring30 resiliently secures the roller 27 in one of the pockets 31, and undernormal conditions the wheel 8 is driven through the ring 22, the link 26and roller 27, the member 19, and the shaft 1st.

Assuming a bottle to be caught in the mechanism as previously related,the obstruction of the wheel 8 overcomes the tension of the spring 30,and the particular driving tooth of the member 19 swings the dog 26outwardly until the roller 27 passes over the end of the tooth,whereupon the spring reacts to suddenly draw the roller into the nextpocket 31, giving the wheel 8 a quick reverse movement and causing therear edge of the preceding tooth of the wheel 8 to engage and push thebottle backward from its dead-centered position. With the displacementof the jammed bottle the mechanism continues in normal operation withoutinterruption.

I claim as my invention 1. In a bottle filling machine having a retaryconveyor and a second conveyor for bringing bottles adjacent said rotaryconveyor, the combination of a rotary wheel adapted to receive bottlesfrom said second conveyor and transfer them to said rotary conveyor, anddriving means for said wheel operative upon obstructing the normalmovement of said wheel to effect a reverse movement of the wheel.

2. In a bottle filling machine having a rotary conveyor and a secondconveyor for bringing bottles adjacent said rotary conveyor, thecombination of a rotary wheel adapted to receive bottles from saidsecond conveyor and transfer them to said. rotary conveyor, a driveshaft, and driving connections between saidshaft and said wheel normallyoperative to rotate said wheel continuously and operative to effect analternate reverse and forward rotation of the wheel when obstructed.

3. Ina bottle filling machine having means for conveying bottlesthereto, the combination of a rotary transferring wheel having pocketsadapted to receive bottles from said conveying means, a drive shaftaxially positioned in said wheel and loosely supporting the same, atoothed member rigidly mounted on said shaft, a swinging dog having apivotal support at one end in fixed relation to said wheel, the free endof said dog normally engaging said toothed member between two teeth, andresilient means for securing said engagement, said securing meanspermitting said dog to swing out of and into successive engagement withthe teeth of said rotating toothed member when the rotation of saidwheel is obstructed and thereby effect a momentary reverse movement ofsaid wheel.

4. In a device of the class described in combination, a bottletransferring wheel, a shaft loosely supporting said wheel, memberrigidly mounted on said shafhaving regularly spaced pointed teeth, a doghaving a pivotal support in fixed relation to said wheel, a rollercarried at the free end of said dog positioned to engage the teeth ofsaid member, and a spring tending to force said roller into suchengagement between said teeth, said teeth being formed to force saidroller outwardly when said wheel is retarded and to impart a reversemovement to said wheel when said roller passes the point of a tooth andis reengaged between the next pair of teeth by the impulse of saidspring.

5. In a device of the class described, in combination, a bottletransferring wheel having a series of peripheral pockets to receive andconvey bottles, a shaft loosely supporting said wheel, a member rigidlymounted on said shaft having radial teeth equal in number to the pocketsin said wheel, a ring rigidly mounted on said Wheel concentrically withsaid shaft, a dog pivotally supported on said ring having a roller atthe free end thereof, said roller being positioned for engagementbetween the teeth of said member and swmgable with said dog forengagement between successive teeth upon the relative rotation of saidmember and said wheel, and resilient means for resisting the 10 outwardswinging of said dog and roller.

In witness whereof I have hereunto attached my signature.

STANLEY W. WILKINSON.
